External component selection is determined by the maximum load current and begins with the selection of the inductor value and operating frequency followed by C IN and C OUT .Main Control LoopDuring normal operation, the internal high side power switch (P-MOSFET) is turned on at the beginning of each clock cycle. The inductor current increases until it reaches the value defined by the output voltage (V COMP ) of the error amplifier. The error amplifier adjusts its output voltage by comparing the feedback signal from a resistive voltage divider on the FB pin with an internal 0.8V reference. When the load current increases, it causes a reduction in the feedback voltage relative to the reference. The error amplifier increases its output voltage until the average inductor current matches the new load current. When the high side power MOSFET shuts off, the synchronous power switch (N-MOSFET) turns on until the beginning of the next clock cycle.Output Voltage SettingThe output voltage is set by an external resistive voltage divider according to the following equation :OUT REF R1V = V x (1)R2where V REF is 0.8V typical. The resistive voltage divider allows the FB pin to sense a fraction of the output voltage as shown in Figure 1.V OUTFigure 1. Setting the Output VoltageSoft-StartThe RT8074 includes an internal soft-start function thatgradually raises the clamp on the COMP pin.Switching Frequency SettingThe RT8074 offers adjustable switching frequency setting and the switching frequency can be set by using external resistor RT . Switching frequency range is from 200kHz to 2MHz. Selection of the operating frequency is a tradeoff between efficiency and component size. High frequency operation allows the use of smaller inductor and capacitor values. Operation at lower frequencies improves efficiency by reducing internal gate charge and transition losses,but requires larger inductance values and capacitance to maintain low output ripple voltage. An additional constraint on operating frequency are the minimum on-time and minimum off-time. The minimum on-time, t ON_MIN , is the smallest duration of time in which the high-side switch can be in its “on ” state. This time is 90ns (typically). In continuous mode operation, the minimum on-time limit imposes a maximum operating frequency, f SW_MAX , of :f SW_MAX = V OUT / (t ON_MIN x V IN_MAX )where V IN_MAX is the maximum operating input voltage.Through external resistor RT connect between RT pin and ground to set the switching frequency f SW . The equation below shows the relation between setting frequency and RT value.The switching frequency vs R RT value can be short with the formula below : f SW (MHz) = K x 0.9 / R RT (k Ω),where K = 3.67 x 105Note that the variation of f SW is ±15%.Figure 2. Switching Frequency vs. R RT ResistorRT80749DS8074-08 November 2020©Copyright 2020 Richtek Technology Corporation. All rights reserved. is a registered trademark of Richtek Technology Corporation.Having a lower ripple current reduces not only the ESRlosses in the output capacitors but also the output voltage ripple. Highest efficiency operation is achieved by reducing ripple current at low frequency, but it requires a large inductor to attain this goal.For the ripple current selection, the value of ΔI L = 0.4 (I MAX )will be a reasonable starting point. The largest ripple current occurs at the highest V IN . To guarantee that the ripple current stays below a specified maximum, the inductor value should be chosen according to the following equation :OUT OUT L(MAX)IN(MAX)V V L 1f x I V ⎡⎤⎡⎤=-⎢⎥⎢⎥∆⎢⎥⎢⎥⎣⎦⎣⎦Using Ceramic Input and Output CapacitorsHigher value, lower cost ceramic capacitors are now becoming available in smaller case sizes. Their high ripple current, high voltage rating and low ESR make them ideal for switching regulator applications. However, care must be taken when these capacitors are used at the input and output. When a ceramic capacitor is used at the input and the power is supplied by a wall adapter through long wires, a load step at the output can induce ringing at the input V IN . At best, this ringing can couple to the output and be mistaken as loop instability. At worst, a sudden inrush of current through the long wires can potentially cause a voltage spike at V IN large enough to damage the part.Slope Compensation and Inductor Peak Current Slope compensation provides stability in constant frequency architectures by preventing sub harmonic oscillations at duty cycles greater than 50%. It is accomplished internally by adding a compensating ramp to the inductor current signal. Normally, the maximum inductor peak current is reduced when slope compensationInductor SelectionFor a given input and output voltage, the inductor value and operating frequency determine the ripple current. The ripple current, ΔI L , increases with higher V IN and decreases with higher inductance :OUT OUT L IN V VI 1f x L V ⎡⎤⎡⎤∆=-⎢⎥⎢⎥⎣⎦⎣⎦is added. For the RT8074, however, a separate inductor current signal is used to monitor over current condition,so this keeps the maximum output current relatively constant regardless of duty cycle.Hiccup Mode Under-Voltage ProtectionA Hiccup Mode under-voltage protection (UVP) function is provided for the IC. When the FB voltage drops below half of the feedback reference voltage, V REF , the UVP function will be triggered to auto re-soft-start the power stage continuously until this event is cleared. The Hiccup Mode UVP reduces input current in short circuit conditions and prevents false triggering during soft-start process.Under-Voltage Lockout ThresholdThe IC features input under-voltage lockout protection (UVLO). If the input voltage exceeds the UVLO rising threshold voltage, the converter will reset and prepare the PWM for operation. If the input voltage falls below the UVLO falling threshold voltage during normal operation,the device will stop switching. The UVLO rising and falling threshold voltage has a hysteresis to prevent noise-caused reset.Over-Temperature ProtectionThe RT8074 includes an over-temperature protection (OTP)circuitry to prevent overheating due to excessive power dissipation. The OTP will shut down switching operation when junction temperature exceeds a thermal shutdown threshold T SD (150°C). Once the junction temperature cools down by a thermal shutdown hysteresis (ΔT SD = 20°C),the IC will resume normal operation with a complete soft-start.Thermal ConsiderationsFor continuous operation, do not exceed absolute maximum junction temperature. The maximum power dissipation depends on the thermal resistance of the IC package, PCB layout, rate of surrounding airflow, and difference between junction and ambient temperature. The maximum power dissipation can be calculated by the following formula :P D(MAX) = (T J(MAX) − T A ) / θJAwhere T J(MAX) is the maximum junction temperature, T A isRT807410DS8074-08 November 2020 ©Copyright 2020 Richtek Technology Corporation. All rights reserved. is a registered trademark of Richtek Technology Corporation.the ambient temperature, and θJA is the junction to ambient thermal resistance.For recommended operating condition specifications, the maximum junction temperature is 125°C. The junction to ambient thermal resistance, θJA , is layout dependent. For SOP-8 (Exposed Pad) packages, the thermal resistance,θJA , is 75°C/W on a standard JEDEC 51-7 four-layer thermal test board. The maximum power dissipation at T A = 25°C can be calculated by the following formula :P D(MAX) = (125°C − 25°C) / (75°C/W) = 1.333W for SOP-8 (Exposed Pad) package.The maximum power dissipation depends on the operating ambient temperature for fixed T J(MAX) and thermal resistance, θJA . The derating curve in Figure 3 allows the designer to see the effect of rising ambient temperature on the maximum power dissipation.Figure 3.

7.28管脚封装二、应用：1.处理过程中的通信2.通信基站3.测试装备4.医疗成像5.视频数字化D数字化三、描述：ADS807是一个高速，宽动态范围，12位通道的数模转换器（A/D）。
这种数模转换器具有高带宽的跟踪和保持特性，而这种特性在奈奎斯特速率的附近表现出了良好的杂散性。
这种跟踪和保持特性的差分本质和A/D转换电路使偶次谐波最小化并且拥有良好的抗共模干扰能力。
而这种跟踪和保持特性一直具有直到信号结束。
ADS807在没有任何外部参考电路情况下，转换器的满量程都是可以使用的。
而内部的参考电路不支持低驱动，且内部的参考电路可以用来改善在多通道系统中的跟踪特性。
ADS807提供了一个超量程指示标志用来指示超出转换器输入满量程的输入信号，这个标志可以用来减少前端增益控制电路的增益。
且其存在一个输出使能管脚允许在PC板上实现复用和可测性。
ADS807采用数字误差校正技术，为需要图像处理的场合提供优良的差分线性。
绝对最大额定值：注意：列在上表“绝对最大额定值”中的这些重要参数可能对装置设备产生永久性的伤害。
长时间使用在绝对最大值的这种情况下可能会影响设备的可信度。
四、静电放电敏感度这个综合电路可能被ESD破坏。
TI公式推荐所有的综合电路要与适当的预防措施配合使用。
不遵守适当的处理和安装程序，可能会造成伤害。
ESD造成的破坏有很多，小到微弱的性能下降，大到整个装置的破坏。
精密的综合电路对这些破坏会更敏感，因为非常小的参数改变都可能引起装置不能满足其发布的规范。
